What do you guys think about AFR 255 heads? i need some new heads and i am looking to get the best bang for my buck i was thinking of going with Meaux heads out of Louisiana but they want like 3600+core for the 6.0 heads. AFR wants less than that with out a core I am planning on waiting to the middle of Jan. when the 255 head comes in a 65cc so i can run pump gas. What do you guys think of these heads i am looking to get some of the best heads you can get but i am a cost concious person. These heads flow 325 so they seem to be pretty good.
Any advise would be greatly appreciated
Thanks

I checked them out at PRI. They look very nice, and I'm sure you'd be happy with them. But, from a race car standpoint, there's some new stuff coming up very soon. The only dislike I had about the AFRs was that you can't customize the casting.

Larry Meaux will not lead you wrong, expsenvise but I've never heard anyone say they got anything less than what they paid for 
$3600? Sounds like a solid roller setup Stage 3 port job. Allan Futral of Futral Motorsports may be able to help you get a set of Heads ported by Larry for a bit less.
I think you will do fine with the AFR's or the Meaux heads.

255? Are you referring to the AFR 225's? There wont be anything bigger than AFR 225's for awhile as I understand it.
I hope to go with a set of the 225s on my 436. I saw them at PRI and was very impressed.

Who is ffhp? never heard of them so i guess the AFR 255's are basically some of the biggest heads made as of now? i was told they flow pretty close to 330 which i figure is damn good +they make there own casting so there is no core required which is good I have heard good about Meaux heads but i have also heard good about AFR's as well. All these choices!! lol

225's are the biggest LSx castings from AFR currently only available in 72cc.

So your doing solid roller?
This is going to be driven on the street or just at the track?
Check out FEAR THE LS1
His motor is built by allen and is running mid 9's all motor.
Allen has a great rep for making things go fast.
With that being said I dont know how you can go wrong with AFR 225 heads. They will defentially make some nasty power, and I believe will be a top notch head. Will they make more power then a very good porters stage 3 job ??????????
Guess we will have to wait and see.
I am gonna guess no, there is just to many other restrictive ways to get air in the motor.
If you see flow numbers of heads and then flow numbers through a LS6 or LSX intake you defentially loose cfm's in other places.

I know west coast cylinder heads did there own cnc with afr cores with 2.100 intake 1.60 exhaust, and were flowing 347 and 247 at .600. These heads were flowed on a 4.125 bore as they are only intended for the big displacement motors. Cost was 3k. Intake cc was estimated to be about 245cc at the time. He is doing some more revisions, so you should get even more out of them. They looked really nice and flow did not fall off at .600. Give them a call if you want the most up to date on them

i would like to build a 408 solid it will be a street car so to say driven to the street races and i want to be able to run pump gas on the motor, of course when i spray the car i know i will have to have race gas. AFR told me that the 225 with the 75cc will have to be run with race gas they also told me that in the middle of january they are making the 225 with 65cc so pump gas can be used.

Lower CR=lower octane, high CR=higher octane (for detonation purposes)

Just to stir the pot alittle....I would say for the money a set of GTP heads would be the best BANG for the buck. Craig has got those down to a art. Basically 440's all day. I know they have a website and that thunder carries them also. Just a idea.....PROVEN RACE WINNER.....
